SUMMARY OF THE INVENTION

[0022] In keeping with these objects and others, which may be apparent, the present invention relates to a universal mission-adaptable set of structural components forming a myriad of useful movable support carts or stationary utility tables, which can be rapidly and accurately deployed in the field with minimal or no tool assembly. The cart may be a convertible, multi-purpose portable cart, for use in camping, hunting, emergency response, search and rescue operations and other outdoors activities, such as for carrying canoes and small boats by hand. It may also carry game, injured parties or be used for transporting gear at outdoors locations. It is a versatile portable cart which can interchangeably function as a movable or stationary medical rescue carrier, cargo carrier, portable canoe or boat cart, which can be assembled with interfitting parts and with minimal fasteners. It can be folded down and transported within the canoe or boat, as a carry cart for transporting game or injured parties over long, rough terrain or snow, or as a gear cart, all of which can be broken down into a carrying position, by hand or by back.

[0023] The cart/utility table is moved by manual pushing or pulling force applied to activate vehicle movement actuators, such as wheels upon terrain or skis upon snow or ice, wherein upon the exertion of force the wheels or skis cause forward or rearward movement of the portable cart.

[0024] The cart/utility table is easily assembled or disassembled by connecting its parts together, or optionally assembled from a pre-set storage configuration in a carry pack to an assembled structure.

[0025] The cart/utility table easily changes from one use to the other. For example, in one embodiment, a hollow cargo well may contain a second loose layer, which turns into a rescue stretcher when the second layer becomes taut when zipped up from a loose, relaxed state within the cargo well to a taut rescue stretcher for carrying injured persons thereon.

[0026] In an alternate rescue embodiment, clamps can be provided on shortened horizontal support members to hold rails to hold medical rescue stretcher rails, and optional handles or pivotable kickstands can be further attached by clamps to the stretcher rails.

[0027] In military applications, the height of the vertical struts can be lowered to keep the injured person on a low profile stretcher close to the ground, to avoid visible detection. In such a case, the handles can optionally easily rotate from a handle carry position to a stationary kickstand mode.

[0028] The portable cart is preferably under thirty (30) pounds, preferably twenty two (22) to twenty eight (28) pounds, so that it can be carried by hand or within a backpack over rough terrain. It is collapsible, so that it can be disassembled and carried in a canoe or small boat, and then reassembled with minimal assembly steps and parts, at another destination along the canoe or boat's journey.

[0029] To prevent flat tires, its wheels are preferably solid core tires, which cannot get flat, or made of cellular materials, such as medium density, micro-cellular urethane, with stainless steel bearings, over which the wheels rotate. A typical wheel has two press fit bearings adjacent to an integrally molded hub. While the typical wheel is about 2-3 inches wide, for transporting cargo or game on sand or granular terrain, the wheels may be wider, such as 4-6 inches in width.

[0030] For maneuverability in snow-filled winter scenes, optional ski members, including skis, are attached to vertical braces having a length corresponding to the radius of the cart's wheels. The vertical ski braces are attached to the vertical struts where the wheel axles attach.

[0031] For hardiness, the material of the structural frame components is preferably a lightweight but resilient and strong material, such as, for example, 60-61 T6 fully anodized aluminum, or stainless steel. In a substantially pre-assembled optional embodiment, in a storage position within a carry bag, the vertical struts are connected to horizontal supports, which are further engaged with rails to hold a cargo well or rescue stretcher. Pivoting of the horizontal supports about each respective longitudinal axis to a position of rest biases the resiliently engaged rails to return to their natural position of use when released from the storage position.

[0032] These pivotable support and strut assemblies can be further strengthened by optional V-shaped braces, which are positioned where each vertical strut meets each corresponding horizontal support member.

[0033] The portable cart/utility table can hold up to 500 pounds, and for manual pulling easily pulls 300 pounds. The portable cart/utility table is durable to carry heavy weight over rough terrain, such as rock-strewn dirt trails or sloping riverbank surfaces.

[0034] To carry a canoe or boat, two horizontal load supports optionally include support cushions upon which the canoe or boat rests. The position of the horizontal load supports can be varied to accommodate various widths of the canoe or boat.

[0035] To function as a game or rescue cart, the frame, such as a pair of U-shaped rails which are joined end to end, is provided upon the horizontal load supports to form a rounded rectangular frame, over which a taunt, but slightly stretchable, bed of fabric is placed, such as canvas or other flexible material, i.e., plastic or netting. The bed includes sewn loops through which portions of the U-shaped rails of the frame are inserted. Other fabric fasteners such as clips, zippers or eyelets can be also used.

[0036] In an alternate embodiment, the boat support cushions are removable from the horizontal load supports and are replaced by a two-piece clamp, which attaches by at least one fastener, such as a pair of screws, to the horizontal load supports of the cart. Conventional stretchers or personal rescue carriers, such as Stokes-type baskets, are clamped to the cart within the clamps on each respective horizontal load support. In this embodiment, the boat support cushions are attached to a thin plate, such as of {fraction (1/8)} inch aluminum or otherwise, which has at least one fastener such as a pair of threaded studs, insertable with the respective hole or holes in the horizontal load supports, so that the boat support cushions can be removed and replaced by the stretcher-bearing clamps.

[0037] To function as a wagon cart with a well for carrying gear, a hollow fabric well, such as of canvas, is draped between the horizontal load members and over and around the front and rear U-shaped brackets. A cover may be provided to cover the gear therein. The well and cover can also be made of other suitable flexible materials, such as plastic, netting or canvas. An optional removable hard bottom substrate floor layer may be provided within the cargo well. While this floor layer may be of any hard material, materials such as lightweight aluminum, wood or marine polymer plastics are preferred.

[0038] Furthermore, the cargo cart may have an optional handle from which may be draped a further optional accessory cargo bag. In the stretcher embodiment, where the upper layer is fastened taut, the handle may have a removable headrest pillow.

[0039] Kickstands may be optionally provided to stabilize the portable cart/utility table during rest or during loading of contents thereon.

[0040] In yet another embodiment, an anti-tipping bicycle attachment is provided to attach the cart to a bicycle while preventing the cart from turning over during transportation.

[0041] In one embodiment, the cart/utility table has two wheels for cargoes weighing from 300-500 pounds. However, for heavier loads, such as for 600-1,000 pounds, an optional double axle version includes two pairs of overlapping wheels for heavier cargo. In this embodiment, the portable cart/utility table uses four wheels in the overlapped configuration, with an optional hard molded canister. In this overlapping, wheeled version, a long axle attaches a pair of front wheels and a short axle attaches a pair of rear wheels through the respective vertical supports, although the length of the axles can be reversed. Using four wheels doubles the carrying capacity of the cart/utility table, and the overlapped positioning of the pairs of wheels maintains a short wheelbase for compactness, for maneuverability and for climbing slopes or ledges.

[0042] In the four-wheeled embodiment, double parallel rails may be provided for additional structural strength. The overlapping, dual axle, four-wheel version gives the user extra pivot points on rough terrain. For example, pushing down upon the optional handle enables the user to lift the further away distal wheels off the ground. Furthermore, pulling upon the handle enables the user to lift the nearer, proximal wheels off the ground.

[0043] The accessory which is placed upon the vertical supports of either the two wheeled or four wheeled cart/utility table, such as the rescue stretcher, the boat cushion, the cargo cart, etc., can be attached permanently or by fasteners to each horizontal load support member of the portable cart/utility table. However, in an alternate embodiment, the horizontal supports have longitudinally extending channels to slide the accessories in on top of the horizontal supports. Furthermore, the accessory, such as a railed rescue stretcher, can be carried by a clamp which itself is attached to the horizontal support by insertion in such a channel, or the stretcher can be dropped in and clamped to a pair of rails forming the horizontal support.

[0044] This clamp upon each horizontal support member may be a one-piece clamp with a full width top section and short end pieces, which mate with and slip into a T-shaped slot channel of the horizontal support member. Alternatively, the clamp may have a full width bottom member which mates with and slides into a T-slot of the horizontal support. In yet another embodiment, two short identical clamp members are inserted into the T-slots of the horizontal member at the two ends. Moreover, the clamping sections can have spring-like gripping action to be retained upon tubular members, such as medical rescue stretcher rails, or the clamps can use fasteners such as fasteners, such as thumbscrews or ball plungers for retention.

[0045] In yet another embodiment, a covered canister can be held in place over the rails of the frame of the cart, in a stable position, by virtue of its weight being held in place upon the rails of the cart, wherein a concave, downward facing channel engages the linear, upper convex support surface of each rail.

[0046] Furthermore, the cart of the present invention can be disassembled and broken down for hand held or backpack transport and it can easily be assembled for its varied uses. Moreover, when a boat or canoe is carried, the cart has a precision balance feature that rotates the wheels to maintain the cart in a horizontal stable position.

[0047] The convertible cart/utility table of the present invention is just one of many modular embodiments which may be made of the present invention. Because of the interchangeability of the parts, the components of the convertible cart/utility table can also be used for assembling a boat hauling cart, a game hauling cart, a wheelbarrow-type hauling cart, a low profile stretcher, a high profile stretcher and a component of a mobile emergency response system.

[0048] Furthermore, in the rescue mode, the convertible cart/utility table allows for one person to transport an injured person instead of two on a stretcher. Because of the convertibility of the cart, when the person is brought to a triage situation for treatment and assessment, the wheels of the cart can be easily removed without tools and replaced by one or more kickstands to stabilize the cart.

[0049] Therefore, in its broadest sense, the present invention is a movable support, such as a convertible cart/utility table, which is collapsible for storage and transport and is able to be assembled and dis-assembled for use in carrying a load, and alternatively functioning as a stationary utility table having stationary legs instead of wheels.

[0050] In one embodiment, the convertible cart/utility table includes a pair of modular load support members which each includes at least one carrying strut extending downward therefrom and a carrier.

[0051] The convertible cart/utility table is preferably carried by handles, which may be extensions of parallel rails constituting the load support member, or the handles may be separate handles having handle extension members nesting in a receiving member of the load support for receiving an adjustably removable handle extension member, such as a tube. The handles may be single grips extending coaxial to the first or the second horizontal frame rails of the movable support.

[0052] In an alternate embodiment, the handles in a pivotable rectangular brace configuration, including a first set of manual grips extending between parallel connectors, which are further connected by a rotatable transverse bar, to enable the handles to be rotated up to a carrying position, or down to a storage position.

[0053] These optional pivotable handles lock in an upper position for hauling the cart, and reverse to a lower position for storage, or in a low profile use, contact the ground surface for operating as a kickstand.

[0054] In addition, the handles may optionally also pivot about their longitudinal axis downward to reach ground level to function as a kickstand for a low profile table cart, or may swing out of the way in a high profile cart when stored during travel or during the stationary utility table mode.

[0055] By “low profile use” it is meant that the movable load support is positioned low to the ground to avoid detection, such as in military rescues. By “high profile use” it is meant that the movable load support is positioned higher up from the ground, such as for example, between 30 and 36 inches, more or less, to allow for access to the load. For example, if the load is an injured person in a rescue operation, the height is high enough to allow medical treatment personnel to conveniently treat the injured person. If the load is cargo, then the height of the high profile movable support, such as a cart, is convenient for stowing and removing the cargo being transported.

[0056] These axially pivotable handles may slide within a hollow support rail, and be locked in place by fasteners, such as spring pins extending through respective holes in an outer wall of the hollow support rail.

[0057] Preferably, the handle includes a first hand grip located coaxially to the handle shaft or tube and an outer second handle grip, which is located parallel to the handle shaft or tube, which is in rigid connection with the coaxial handle grip. Both parallel hand grips are connected by parallel brace members laid perpendicular to the hand grips. The handle member is lockable in at least two positions, such as an upward position for hauling the convertible cart/utility table and a downward position for using the handle as a kickstand in a low profile embodiment, or for storage in a high profile embodiment.

[0058] These handles may be locked in place with a spring pin.

[0059] The longitudinally extending structural frame rails of the movable support can each accommodate a handle extending therefrom, each frame rail having a connecting end and a handle attachment end, and a plurality of spring pin apertures for attachment of additional members.

[0060] In a preferred embodiment, there are at least two spring pins, wherein a spring pin of the plurality of spring pins reversibly protrudes a spring pin aperture of the plurality of spring pin apertures located on each respective frame rail, such as a first horizontal tube.

[0061] Preferably, for knockdown transport, each frame rail may be made of several components, such as a longitudinally extending mid section joined at each opposite end to longitudinally extending first and second connecting end portions. A first spring pin aperture is located on each lateral side of the connecting ends of the first horizontal tube and the second horizontal tube; and a second spring pin aperture is located on each top side of the connecting ends of the first horizontal tube and the second horizontal tube, a distance farther from the connecting end than of the first spring pin aperture. Other pin locations are applicable.

[0062] These assembled frame rails together accommodate optionally one or more clamps, with at least one clamp in communication with a first horizontal tube and at least one other clamp in communication with the second horizontal tube, with both tubes forming the frame rails of the movable load support.

[0063] In a further alternate embodiment, one or more transverse support bars, preferable at least two transverse support bars, are substantially perpendicular to the pair of longitudinally extending frame rail tubes, and may optionally be in communication with a clamp holding a carrier in removable communication with the clamp or clamps. The carrier may be a rescue stretcher, Stokes carrier, cargo bin, open cargo hauling well, rack or other load support means.

[0064] The clamp may be attached to a strut through which accommodates axles therethrough for movement actuators, such as wheels.

[0065] Optionally the clamp may be at least one clamp, reversible for accommodating a range of sizes of carriers, including a bottom surface, an opposing top surface, and a inside surface, a clamp front surface and an opposing clamp rear surface. The bottom surface includes a plurality of grooves for optionally receiving one of the horizontal support tubes of the frame rails, with the reverse top surface including at least one groove for optionally receiving a horizontal support tube. This reversible clamp has a first bore extending from its top surface to its bottom surface, for allowing a bolt to pass therethrough. The reversible clamp also includes a rail-accommodating aperture extending from the clamp's front surface to the clamp's rear surface for receiving a horizontal support tube of a frame rail, and the reversible clamp has a tightening knob for securely attaching the clamp to each respective horizontal support tube;

[0066] The clamp also includes a latch to tighten a load support, such as a stretcher or other rail in place. So that the latch does not become loose, the threaded securing bolt of the latch, which is threaded into a threaded bore of the body of the reversible clamp, includes a bottom flange wider than the threaded bore, which includes a reciprocal flange recess to accommodate the flange of the threaded securing bolt. An optional fixed nut or flange is located at the end of the bolt, for preventing the separation of the joinable latch and main body parts of the reversible clamp and the bolt from the clamp.

[0067] In a preferable embodiment, the clamp may be a heavy-duty clamp having a lower portion having a first concavity for insertion above the horizontal support tubes and a second concavity for slidable and removable insertion of a carrier or a second carrier, a top surface and a guide boss for removable attachment of an upper portion. The upper portion has a third concavity for slidable and removable insertion of a carrier and a guide recess for removable attachment to the lower portion. The heavy duty clamp includes a first latch rigidly connected to the clamp's lower portion, in communication with the first concavity for gripping the horizontal support tube of a frame rail of the load support carrier securely.

[0068] The heavy duty clamp also preferably has a second latch, preferably at an upper end, which second latch is rigidly connected to an upper portion of the heavy duty clamp in communication with the third concavity for gripping the load support carrier securely.

[0069] The heavy duty clamp may optionally support one or more rails holding a fluid catch under the load support carrier, to catch blood and other body fluids if the load support carrier holds an injured person being medically treated thereon.

[0070] This second latch includes a lever latch for manual securing of the load support carrier and a clamping jaw for forming a frictional contact force between the latch and the frame rail of the carrier.

[0071] When the carrier is a stretcher secured to the convertible cart/utility table, the pitch of the stretcher can be adjusted, such as for example, to raise or lower the head of the person being treated. In this case, the stretcher carrier has a front end and a rear end, wherein the front end of each rail is secured to a respective upper hook receptacle portion of the clamp and the rear end of each frame rail of the carrier is secured to a respective lower hook portions of the clamp, resulting in an elevation differential between the front end and the rear end of the second carrier. The clamps come in pairs so that the front and rear clamps on each side are equidistant from each other in length, with each secured to opposing horizontal support tubes of each frame rail.

[0072] In such a case of the head portion of a medical stretcher or other carrier being raised higher than an opposite foot end, the height of the respective head and foot portions can be varied by placing the foot end in the lower hook portions of the foot clamps and the head end in the higher hook portion of the heavy duty clamp. Optionally, the height can be further varied by varying the height of each kickstand, wherein the rear kickstand is in a position of the clearance being a minimum, and the front kickstand is in a position of the clearance being a maximum, resulting in maximum height differential between the front end of the carrier and the rear end of the carrier.

[0073] Additionally, the diameter of the upper latch jaw is effectively less then the inside diameter of the rail support concavity of the clamp for allowing the jaw to accommodate a change in pitch of the carrier, in case the carrier has to be tilted, such as for raising the head of an injured person being treated upon the load support carrier. This latch jaw includes cylindrical portions and a contact portion including a concave surface for evenly contacting the convex surface of the carrier's frame rail.

[0074] Optionally, the kickstand may be a pair of kickstands, namely a front kickstand and a rear kickstand, adjustable in width and insertable through the clamping means and clamped onto each end of each horizontal support frame rail and extending substantially vertically therefrom.

[0075] For further strength of the movable support in a stationary position of use as a utility table, the kickstand may include a substantially vertical left leg, substantially vertical right leg, and a kickstand connecting bar detachably extending horizontally between the left and right legs. Each of the left and right legs of the kickstand may include a lower end and a height adjustable member insertable to the legs by means of a swivel joint for allowing the legs to rotate freely.

[0076] The height adjustable members adjust the height of each leg, preferably by insertion of a first pin, such as a locking pin or a spring pin, insertable within a selected aperture of a plurality of pin apertures in substantially vertical orientation, wherein the height adjustment member is removably insertable into each leg for a predetermined incremental height interval, such as about one inch.

[0077] Besides this macroadjustment of the kickstand leg by selective insertion of the pin into a selected aperture, the height can be adjusted by a microadjustment means, including the kickstand having a screw end and the lower end of the leg includes a receptacle, for the screw end, for fine adjustment of the height of the movable support, where the distance between the edge of the leg of the kickstand and the lower edge of the height adjustment member is a clearance distance.

[0078] The heavy duty clamp also includes an optional outside surface having a hinge for removably attaching at least one rotatable swivelable accessory therefrom, wherein the accessory is an examination or surgical lamp having a flexible or hinged neck, an instrument tray, an arm or leg limb platform support or a gravity or pump fed intravenous (IV) pouch support having an insertable vertical rod and a component for insertion into the vertical rod into the hinge.

[0079] The hinge accessory may include a splitting attachment having an insertion pin for removable and rotatable communication with the hinge, and at least two hinges extending substantially vertically for additional components in a stacking arrangement, such as, for example, one instrument tray being elevated above another instrument tray.

[0080] If there is a person with blood loss during surgery in the field, this convertible cart/utility table can also have an auxiliary fluid catch draining fluids into a closed shallow bucket.

[0081] In addition, medical accessories and a power pack for lighting and for instrument power can be attached to the cart.

[0082] In the basic cart mode a transverse member connecting the load support members is not necessary, as the downwardly extending struts accommodate the axles for one or more pairs of wheels, which act as transverse support members for the cart in its basic transportable cart embodiment.

[0083] The load support member itself may be a) a resting member supporting a load thereon or, b) it may be a clamp. The clamp may be adjustable by a handle, which may have a stop to prevent complete unscrewing of the stud of the handle so that the clamp cannot come apart. The clamp can be a pair of jaws, or it can be a longitudinally extending slider clamp where the load support slides into a recess between two overhanging cantilevered members extending upward from the base.

[0084] The convertible cart/utility table is also useful in military and emergency situations. For example, in addition to rescue of injured military or civilian personnel, the cart may be used in areas contaminated by toxic substances or weather related disasters. Besides moving an injured party in a triage situation to a treatment area in a detoxification environment caused by a weapon of mass destruction such as gas, smoke or other noxious particles, there may be a necessity for a wash of the persons so the contaminated persons can be brought by the convertible cart/utility table to a wash area where they are first immediately washed of surface contaminants. In this weapons of mass destruction treatment facility there can be any one of these pieces of equipment to wheel the injured persons to decontaminate them. If they are not ambulatory, for any further treatment they can be brought to the medical facility.

[0085] The medical facility can set up as a fully operational ten (10) or more bed field hospital treatment facility with ten (10) or more sets of bins carried on ten or more carts, wherein each upper most bin shell container of each set of containers for each bin can be tilted and moved can be moved from a horizontal carrying position to a vertical stand upright position with drawers extending outward therefrom. A mobile hospital is modular in its design. If there is a need for more than ten (10) beds, then increment units of ten can be provided and deployed to a site. For rapid deployment, the convertible cart/utility table with cargo hauling bins can be hauled by all terrain vehicles in a rapid manner.

[0086] In addition, the convertible cart/utility table easily converts without tools from either a wheeled embodiment to a fixed table embodiment wherein the wheels are replaced by one or more kickstands. When in the utility table mode, the cart can have extending therefrom, by clamps, one or more swivelable platforms supporting injured limbs of a person or medical supplies such as an instrument tray, a light, an I.V. tube pole, etc. In this case, the platform is pivotable, but not removable. It pivots like a hinge to any desired position.

[0087] Auxiliary transverse bars can be added when in the fixed table embodiment. Additionally, there are micro and macro adjustments of the height of the cart depending on the need for access to the injured person on the cart. For example, there are macro adjustments in one-inch (1″) increments to raise the cart up and there is also a micro adjustment by a threaded member for up to a one-inch (1″) of micro adjustment.

[0088] To hold rescue stretchers or other carrier rails, a heavy-duty utility clamp has a concave hook portion for dropping in a stretcher rail and a lower concave portion for dropping in a rail holding an auxiliary fluid catch basin or sling. However, one end of the stretcher can be put in a lower concave hook of the heavy-duty utility clamp to slant the position of the stretcher. Furthermore, by adjusting the transverse bars and/or the axles, the width of the utility table can be widened, so it is totally adjustable to fit any size carrier or stretcher.

[0089] In addition, in order to raise the head of an injured party, raising one end and lowering the other end can slant the table portion. A preferable ten-degree (10°) adjustment can be done with the adjustable foot height and then there is an additional five degrees (5°) by adjusting the heavy-duty clamp and raising or lowering one end of the stretcher on the utility table.

[0090] Hinged platform arm or leg board platforms may extend from a clamp attached to the frame rail of the utility table. The platforms swing out radially in a horizontal plane, to provide maximum adjustability for the position of the limbs of a victim or for the positioning of medical/surgical accessories, such as intravenous stands, instrument trays or examination lamps. It is further noted that attached to the auxiliary arm board platforms may be poles for supporting an intravenous fluid pack or a tent to repel insects from the treatment environment. While other suitable measurements may be used, these arm board platforms are preferably six inches (6″) wide and the leg boards approximately eight inches (8″) wide.

[0091] The convertible cart/utility table also optionally includes a clamping means, which may be a latch, a pair of clamping jaws, a longitudinally extending slotted extrusion or a receptacle.

[0092] The axle-carrying struts each have a lower end with an axle mounting means at the lower end and at least one axle extending through each axle-carrying vertical strut. Each axle has at least one vehicle movement actuator, such as a wheel or a ski, of a pair of vehicle movement actuators attached at opposite sides of the convertible cart/utility table, which also has a carrier attachable to the load support member, wherein when the carrier supports a load thereupon. Such a carrier may be a hollow well, a bin, a pair of rails, a rescue stretcher or Stokes carrier or other support surface or container optionally the carrier may be rotatable from a horizontal position of travel to an upright position as a shelved cabinet.

[0093] The parts are easily assembled and disassembled without the necessity of tools. For example, the parts can be held together by clamps or receiving receptacles including a spring pin aperture for receiving a push pin for secure interconnecting of a component of the convertible cart/utility table, such as the handle tube within the receiving member of the load support member. The components can also be held in place by pins or other fasteners positioned within diametrically opposed transverse holes for allowing a through pin to extend therethrough. PINS

[0094] While in simple embodiments the convertible cart/utility table includes a single pair of wheels attached by struts extending down from the load support members, in other embodiments the convertible cart/utility table includes two pairs of axle load supports and four vehicle movement actuators, such as wheels.

[0095] To convert from a movable support, such as a convertible cart to a stationary utility table, the downwardly extending axle-supporting struts are detached by their clamping means from the load support members, and replaced by stationary kickstands, which contact the ground to maintain the utility table in a stationary position.

[0096] One kickstand may be used with the wheeled struts still in place, although for maximum stability all wheeled struts are replaced by kickstands.

[0097] The kickstand may be a single rod extending from the load support member to the ground, or it may be an H-shaped or U-shaped pair of downwardly extending rods connected by a widenable transverse member, to vary the width of the convertible cart/utility table.

[0098] The convertible cart/utility table may also include at least one cargo bin removably connected to the load support member.

[0099] Each of the cargo bins preferably includes a top shell container of a plurality of shells, each having a top outer surface and an opposing top inner surface; a bottom shell having a bottom outer surface and an opposing bottom inner surface. The top outer surface includes a boss arrangement and the bottom outer surface includes a recess arrangement corresponding with the boss arrangement, for aligning a plurality of the cargo bins to be vertically stacked one on top of each other in a caravan of bin-hauling carts. There may also be one or more intermediate shell containers.

[0100] The bin of the convertible cart/utility table has one or more latches for removably connecting the top shell to the bottom or intermediate shell, wherein the latch is optionally lockable. Preferably, each bin is made of a sturdy, lightweight material, such as fiberglass.

[0101] A top shell can be removed from the stack of bins and stood upright as a medical or other supply cabinet, which includes slidable drawers, anchored to and within the top shell of the cargo bin. Preferably, the top inside surface and the bottom inside surface of the shells of the bin each includes a foam lining for limiting the movement of contents within the cargo bins. Additionally, the shells further include one or more optional removable interior containers.

[0102] The mission-adaptable components may therefore deploy a portable cargo bin having a cabinet system and at least one locking latch, and be secured to the collapsible cart/utility table, in a method including:

[0103] i) in the case of the collapsible cart/utility table having vehicle movement actuators, such as wheels, securing the wheels in place to prevent movement,

[0104] ii) applying force to tilt the collapsible cart/utility table about a first axis until a first rest position is reached, wherein the force is optionally applied to a pair of handles in connection with the collapsible cart/utility table, and the first axis of tilt being the vertex formed of the intersection between the bottom outer surface and a bottom front surface;

[0105] iii) unlatching the straps holding the shells of the bin;

[0106] iv) applying force to tilt the collapsible cart/utility table about a second axis until a second rest position is reached, wherein the second axis of tilt is the vertex formed of the intersection between the top outer surface and the top front surface;

[0107] v) disengaging the latch or latches; and

[0108] vi) separating the top shell from the bottom shell and the portable cart/utility table, allowing it to return to the first rest position or optionally to return fully to the initial standing position.

[0109] The convertible cart/utility table may also include a modular load support member which includes at least one axle-carrying strut extending downward therefrom, a receiving member for receiving an adjustably removable handle tube and optionally a clamping means.

[0110] The clamping means may be an extrusion slider clamp rigidly attached to the modular load support member, having a top clamp surface, an inside edge and an outside edge. The top clamp surface further includes a groove formation aligned with the inside edge and the outside edge for horizontally receiving a carrier therein.

[0111] In this case, the axle carrying struts have a lower end with an axle mounting means at the lower end, at least one axle extending through each axle-carrying strut. Each axle has at least one vehicle movement actuator of a pair of vehicle movement actuators attached at opposite sides of the cart and a carrier attachable to the clamp, wherein when the carrier supports a load thereupon.

[0112] The axle carrying struts may each includes a lower end with an axle mounting means at the lower end, at least one axle extending through each vertical strut and a plurality of transverse holes for resisting impact. A carrier is attachable to the load support member, wherein when the carrier supports a load thereupon. Additionally, each axle carrying strut may have a pair of support trusses for increased load support, the trusses being rigidly connecting the axle carrying support and the extrusion clamp.

[0113] As a result, the convertible cart/utility table is mission adaptable for a variety of missions, and is not mission specific, such as for one particular task. The components break down into interchangeable parts, and are easily transported or stored for adaptability to a myriad of tasks in both friendly and hostile environments.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0224] As shown in the drawing FIGS. 1-70, the present invention is directed to a mission-adaptable set of components forming a convertible cart/utility table. For example, the present invention may include foldable cart 1, having a load support for carrying a load, such as a boat, such as a canoe, which can also function as a game cart or a wagon for carrying gear in outdoor field applications.

[0225]FIG. 1 shows cart 1 in a disassembled storage position with a pair of horizontal load support members 10 laid parallel adjacent to each other, supporting wheels 30 thereon. Wheels 30 are secured in place by a transverse connecting rod 31 through wheel hubs 30 a and by one or more load securing straps 50. Disassembled storage cart 1 is inserted within carry bag 120, which includes ledge 121 and fabric loops 122 for holding bracket members 60, 70 and handle 80 outside of carry bag 120.

[0226] To transport portable cart 1 by hand carry straps 124 are attached to carry bag 120. Conversely as shown in FIG. 2, to transport portable cart 1 upon the back of a user, carry straps 124 are attached to carry bag 120, which supports portable cart 1 in a weight bearing manner, or else horizontal support members 10 are inverted to support portable cart 1 in a weight bearing manner, and carry bag 120 covers portable cart 1 in a non-weight bearing manner.

[0227] To be disassembled in a carry position, U-shaped bracket rails 60,70, wheels 30 and axle members 32 are inversely attached to horizontal load supports 10 to comprise a folded manually transportable cart.

[0228] As shown in the exploded view of FIG. 3, in the storage position, in a preferred embodiment, cart 1 includes a pair of parallel, spaced apart inverted horizontal load support members 10. Support members 10 each have a front-end 10 a and a rear end 10 b. The front and rear ends 10 a, 10 b each have at least one axially placed receptacle aperture 12 extending longitudinally within each load support member 10, for holding structural components therethrough in a storage position, such as axle members 32 for wheels 30. In this storage position, axle members 32 are also inserted within aperture of 33 of axle connector 34.

[0229]FIG. 3 also shows horizontal load support members 10 having preferably a generally upside down U-shaped configuration when viewed in cross-section, wherein a generally flat member 10 c has downwardly extending flanges 10 d, 10 e including one or more linearly extending slots 10 f for insertion of holding straps 50 therein.

[0230] Although apertures 12 are shown in the drawings, it is contemplated that other configurations may be applicable to horizontal load support members 10, so long as other members, such as rails 60, 70 and so forth, may be attached thereto by fasteners, preferably in an axis parallel to the axis of horizontal support members 10.

[0231] While size may vary, support member 10 is preferably sixteen (16) inches long and two and a quarter (2.25) inches wide. Each flange 10 d, 10 e extends down about one (1) inch from flat member 10 c. Slots 10 f are preferably 2.125 inches wide and 0.1875 inches high, to accommodate straps 50, such as, for example, standard 2-inch wide fabric straps.

[0232]FIG. 3 also shows vertical struts 20 optionally having at least one small hole 22, such as kickstand receptacle aperture 22, for insertion of optional kickstand 40 therein.

[0233]FIG. 3 also shows horizontal load support members 10 being respectively demountably attached to a pair of vertical struts 20, having apertures 21 and 22. In one embodiment, horizontal load support members 10 can be demountably attached to vertical struts 20, but in an alternate embodiment they can be permanently affixed to each other, such as in the alternate embodiments shown in FIGS. 3A and 3B.

[0234] Moreover, while preferably horizontal struts are U-shaped, as in FIG. 3, in alternate embodiments other configurations can be used, as long as vertical strut 20 can be attached to horizontal support member 10.

[0235] For example, in FIG. 3A vertical strut 20′ is in a unified T-shaped member with horizontal support member 10′. In FIG. 3B, vertical struts 20, and horizontal support members 10′ are attached by weldment 20″. In FIG. 3C, vertical strut 20′ is inserted in hole 10″ of horizontal support member 10′, and attached by fastener 10′″, such as a screw or other fastener. In these alternate embodiments shown in FIGS. 3A, 3B or 3C, horizontal load support members 10′ may be solid in cross sectional configuration. One such configuration shown in FIGS. 3A, 3B and 3C is that of a parallelepiped, namely a solid form, all of whose sides are parallelograms, such as rectangles, and whose opposite sides are parallel to one another.

[0236] In another embodiment vertical strut 20 may be adjustable in length with a sleeve containing a telescopic shaft (not shown) and with a spring urging the shaft in and out of the sleeve, with a lock provided.

[0237] Kickstand 40 is shown deployed in FIG. 4.

[0238] Kickstand 40 is secured in place by a fastener, such as nylon set screw 37. Setscrews 37 also hold axle members 32 in the storage position through vertical struts 20.

[0239] Vertical struts 20 are preferably made from 1½×2-inch solid bar stock anodized aluminum, or stainless steel. Vertical struts 20 are preferably about 10.25 inches long, 2 inches wide and 1½ inches in depth.

[0240] Also shown in FIG. 3, the plurality of optional larger holes 21, such as holes, which are 0.765 or 1.625 inches in diameter, are located on a front side of vertical strut 20. Smaller hole 22 on the bottom accommodates kickstand 40, which is preferably a hollow aluminum tube of 0.75-inch diameter and 16 inches in length.

[0241] Optional larger holes 21 within vertical strut 20 are provided for weight reduction of portable cart 1.

[0242] On a side 23 transverse to the front 24 of each vertical strut 20, at a lower portion 20 a thereof, is provided a further hole 25 of about 1-inch in diameter for insertion of each axle member 32 therethrough. Hole 25 has a permanently affixed, bushing 26 therein, such as a PVC (polyvinyl chloride) bushing, to prevent wear and tear of each aluminum axle member 32 by the aluminum surface of hole 25.

[0243] As also shown in FIGS. 3, 4 and 6, each wheel 30 is demountably attached at an end, respectively, to a pair of axle members 32, with axle members 32 extending inwardly from and demountably attached to lower portion 20 a of the respective vertical struts 20, wherein axle members 32 are in a transverse relationship to horizontal load support members 10. Fasteners, 36, such as cotter pins, hold each wheel 30 upon each axle 32.

[0244] Each axle member 32 is received within each hole 25, of each lower portion 20 a of each vertical strut 20. A compression groove 27 exists from the underside of vertical strut 20 to hole 25 and continues to further through hole 27 a, providing for compression of lower portion 20 a of vertical strut 20.

[0245] To accommodate narrow or wider cargo, such as watercraft of varying widths, the distance between vertical struts 20 can be varied along the axle length by loosening and tightening the tightening member 28 and moving vertical struts 20 laterally apart or towards each other along axle members 32.

[0246] Although optionally a one-piece axle may be used (not shown), preferably the pair of axle members 32 are held in opposite axial orientation by straight rigid axle connector 34. Axle connector 34 has tightening member 35, and a pair of receptacles 33 at the respective two ends of axle connector 34, so that axle members 32 respectively extend outwardly from, and are demountably attached within, the axle connector receptacle bore 33.

[0247] While the axle may be optionally a one-piece axle, such as shown as reference numeral 606 in FIG. 33 herein, preferably the pair of connected oppositely extending axle members 32 form together an axle for wheels 30.

[0248] Each axle member 32 is made of solid round stock of anodized aluminum or stainless steel, approximately 0.75 inches in diameter. At the wheel-supporting end 32 a, the diameter is about 0.59 inches in diameter with shoulders 32 b of about 0.08 inches in height, transverse to the axis of axle member 32. These shoulders 32 b provide a resting surface to prevent axial movement of wheel 30 upon axle member 32.

[0249] As shown in FIG. 7, each wheel 30 rotates about press fit bearings 32 b, while each wheel 30 is positioned upon each respective axle member 32 of FIG. 8. As shown in FIG. 6, at the opposite end of one axle member 32, there is provided a hollow, threaded recess 32 c of about 0.75 inches deep, to accommodate a connecting threaded member 32 d of other axle member 32, to axially connect both axle members 32 together within axle connector 34, with a wheel 30 at each end.

[0250]FIGS. 8 and 9 show how axle connector 34 is compensated along groove 38, thereby locking axle members 32 within bushing 39, which is within receptacle bore 33 of axle connector 34, by tightening of tightening bolt 35 a of tightening member 35. Preferably bushing 39 is a PVC (polyvinyl chloride) bushing. Groove 38 is preferably {fraction (1/16)} to {fraction (1/8)} inch, in width, which allows for the compression of axle connector 34 around axle members 32. Tightening bolt 35 a is inserted within a conventional receptacle which is a through hole at the proximal end and which is tapped with threaded grooves at the distal end, to allow for compression of axle connector 34.

[0251]FIGS. 4 and 6 also show at least one kickstand 40, preferably a pair, respectively extending horizontally rearward from each lower portion of vertical struts 20. Each kickstand member 40 extends rearwardly from the at least one kickstand receptacle aperture 22 of respective vertical struts 20 and each kickstand 40 is demountably attached within each respective kickstand receptacle aperture 22. Each kickstand member 40 is preferably contoured so as to contact the ground to stabilize portable cart 1 is a parked position of rest.

[0252] As shown in FIG. 5, to hold a canoe, game or cargo in place upon cart 1, one or more adjustable load-securing straps 50 are slidably attached to both respective horizontal load supports 10 in a transverse relationship to load supports 10. Straps 50 are preferably reinforced flexible canvas straps of about 2 inches in width.

[0253] To complete portable cart 1 as a canoe or boat cart, FIG. 4 shows support cushions 13 mounted upon respective horizontal load supports 10. Support cushions 13 are flexible, such as of rubber or foam, to support the weight of boat 2 thereon.

[0254]FIGS. 10 and 11 show the precision balancing of boat 2 upon cart 1, wherein the placement of boat 2 upon cart 1 causes cart 1 to rotate from a position of rest in FIG. 10 to a horizontal load position of FIG. 11, in the direction of the arrow.

[0255]FIGS. 12-17 show another embodiment that converts portable cart 1 into a game cart. Alternatively, FIGS. 18-20 show how to convert cart 1 into a cargo wagon with a hollow well. First, in either situation, carry frame 55 is secured to horizontal load supports 10. Although a one piece, generally rectangular frame (not shown) may be used, preferably frame 55 includes a pair of U-shaped brackets 60, 70 joinable together to form frame 55.

[0256] Various fasteners may be provided to horizontal load supports 10 to carry objects, such as carriers, thereon.

[0257] Alternatively, for example, a clamp maybe provided to horizontal load supports 10 to carry a frame of a discrete transportable carrier directly thereon, as disclosed hereinafter with respect to FIGS. 21-24. In that case, instead of the frame being integrally part of the portable chart, as in FIGS. 12-17, in FIGS. 21-24, the frame is clamped to the horizontal load supports 10 of portable cart 1. Other fasteners may include longitudinally extending channel slots, such as in FIGS. 33-39 described further below.

[0258] Meanwhile, further with respect to FIGS. 12-17, U-shaped front bracket 60 extends horizontally forward from front-end receptacle apertures 12 of horizontal load supports 10, wherein front bracket 60 is demountably attached within front-end receptacle apertures 12 at one end of horizontal load supports 10.

[0259] U-shaped rear bracket 70 extends horizontally rearward from oppositely positioned rear end receptacle apertures 12 of horizontal load supports 10 and rear bracket 70 is demountably attached within each oppositely positioned rear end receptacle aperture 12 of horizontal load supports 10.

[0260]FIG. 13 shows how frame 55 is secured to cart 1. Each distal end of U-shaped front bracket 60 is inserted through apertures in respective ends 10 b of horizontal supports 10 until each distal end engages a corresponding hole in each vertical support 20, where they are held in place by pins 29. Pins 29 engage lateral holes 18 in horizontal supports 10 and corresponding through holes 19 in distal ends of U shaped brackets 60. Likewise, each distal end of U-shaped rear bracket 70 is inserted through apertures in respective ends 10 a of horizontal supports 10 until each distal end engages a corresponding hole in each vertical support 20, where it is also held in place by a pin 29. Pins 29 engage lateral holes 18 in horizontal supports 10 and corresponding through holes 19 in distal ends of U shaped brackets 60, 70 of frame 55.

[0261] U-shaped brackets 60, 70 are preferably of hollow, anodized aluminum tubing of about 0.75 inches in diameter. The length of each distally extending side member thereof is about 23.50 inches and the width of the cross bar connecting the distal side members is about 21.63 inches. About 0.75 inches from each distal end is a scoring, to accommodate a clamp thereon, to form frame 55.

[0262] As shown in FIGS. 12 and 15 for pulling or pushing game or cargo upon portable cart 1, handle 80 extends rearwardly at an upward angle from joints 71 of either U-shaped rear bracket 70 for pushing portable cart 1, or from front U-shaped bracket 60 for pulling portable cart 1 (not shown). Furthermore, handle 80 may be permanently attached to either U-shaped bracket 60 or 70, or handle 80 may be removable and demountably attached to either front U-shaped bracket 60 or rear U-shaped bracket 70.

[0263] Handle 80 has preferably two aluminum tubing connecting members about 22.5 inches in length, connected by a hand accommodating transverse bar of solid aluminum, and is 17.5 inches in width. Handle 80 includes connectors 81, having distal sleeves, such as PVC (polyvinyl chloride) sleeves 82, permanently affixed thereto, which are insertable within joints 71 by locking member 72, having threaded member 72 a which passes through bore 71 a of joint 71 and bore 81 a of handle 80. Compression groove 73 exists in joint 71, providing compression of joint 71.

[0264] Handle 80 may optionally have an auxiliary extension member and clamp (not shown), so that it can be attached to the rear frame of a bicycle (not shown), to pull portable cart 1.

[0265] To carry game 3, as shown in FIG. 17, or to carry an injured person in a rescue operation, FIG. 12 shows portable cart 1 having fabric stretcher 100 stretched tautly between horizontal load members 10 and preferably mounted over and around front and rear U-shaped brackets 60 and 70 of frame 55, by threading brackets 60, 70 through fasteners such as sewn-in loops 102 of fabric stretcher 100, which may alternatively be made of plastic or other taut load bearing material. Other types of fasteners can be used. For example, FIG. 14 shows that loop 102 a is openable, and closed by fastener, such as zipper fastener 102 b.

[0266] As also shown in FIG. 12, handle 80 may include a pair of posts extending obliquely off of a horizontal axis of portable cart 1, wherein a head rest cushion 85 extends between the posts to support the head and neck of an injured person being transported upon stretcher 100.

[0267]FIGS. 18-20 show that to carry cargo, hollow fabric cargo well 110 is attached in the same manner to frame 55. Hollow cargo well 110 may also alternatively be made of plastic or other taut load bearing material, and covered by cover 112. FIGS. 18 and 19 also show wider wheels 130 for use on sand or granular terrain.

[0268] Assembly and Disassembly

[0269] The various embodiments of the mission adaptable multiple-purpose portable cart/utility table can be quickly and easily assembled and disassembled.

[0270] For example, for making a canoe cart from the disassembled portable cart 1, wheel-retaining members, such as cotter pins 36, are taken out of axle members 32 in their stored position, and wheels 30 come out. Axle members 32 are then removed from between vertical struts 20. The axle members 32 are then clamped in a horizontal use position into receptacles 33 of rigid axle connector 34. Axle members are inserted between vertical struts 20 and locked in place. Wheels 30 are placed upon axle members 32 and secured by cotter pins 36. Kickstand 40 is loosened from its rest position and placed in place in receptacles within vertical struts 20. Canoe supporting cushions 13 are installed upon horizontal load supports 10 to support a canoe or boat thereupon. Straps 50 hold the canoe or boat installed upon cushions 13 in a secure transportable position.

[0271] To convert portable cart 1 into a game cart as in FIG. 17 or a rescue cart as in FIG. 12, kickstands 40 are removed and fabric stretcher 100 is installed on U-shaped frame members 60, 70 of frame 55 frames by fasteners such as sewn loops 102 thereof. U-shaped frame members 60, 70 are placed on horizontal load supports 10, and kickstand members 40 are installed as braces for fabric stretcher 100. Straps 50 are then installed to securely hold game or an injured party upon stretcher 100. Then handle 80 is installed upon U-shaped bracket 60 or 70 of frame 55 to pull or push portable cart 1.

[0272] To convert portable cart 1 into a wagon to haul cargo, as in FIGS. 18 and 19, fabric stretcher 100 is removed and hollow well 110 is installed over U-shaped members 60, 70 of frame 55.

[0273] To make the portable chart 1 portable again, the components are disassembled in reverse into bag 120. Strap or straps 50 are used as a carry handle or for backpack shoulder loops.

[0274] While the rescue stretcher shown in FIG. 12 has its own customized stretcher 100, in another embodiment shown in FIGS. 21-24, to convert portable cart 1 to a retrofit disabled person-bearing transportable carrier cart for search and rescue operations, using conventional railed stretcher 230, support cushions 13 are removable from horizontal load supports 10 and replaced by clamping assembly 200. Clamping assembly 200 includes lower jaw 202, and upper jaw 204. While different jaw configurations can be used, the embodiment shown in FIGS. 21-24 shows each having longitudinally extending recesses 206 and 208 therein to grip perimeter frame rails of a load supporting transportable carrier, such as conventional railed stretcher 230 therebetween, as shown in FIG. 23.

[0275] Lower jaw 202 of clamping assembly 200 includes an engaging surface 210 with threaded studs 212 which are inserted into through-holes 214 of load supports 10, and permanently locked with nuts 216. Upper jaw 204 is provided with a pair of oblong through-slots, 218, to allow upper jaw 204 to slide on upper surface of lower jaw 202, when threaded T-handles 220 are loosened. As shown by the arrows in FIG. 22 this sliding action allows for quick removal of any stretcher frame rail secured between jaw assembly 200.

[0276]FIGS. 23 and 24 are perspective views of a typical stretcher 230, and a Stokes-type rescue basket 240, securely clamped to portable cart 1 utilizing the previously described clamping assembly 200.

[0277] As shown in FIG. 25 in this embodiment, instead of being permanently attached to each horizontal load support 10, removable support cushion 13 is permanently attached to removable plate 302 with an adhesive 304. This cushion assembly is removably attachable by nuts 316 and threaded studs 312, to each horizontal load support 10.

[0278]FIG. 26 illustrates portable cart 1, outfitted with a plurality of racking assemblies 400, each comprising a rail clamp 410, an upstanding post 424, and a hanger clamp 430. Rack assembly 400, when used in conjunction with additional rack assemblies 400, allows for transportation and quick removal of essential hunting gear such as a chair stand 440, archery equipment 441, and rifle 442. Other related items such as knapsacks and bedrolls may be supported by rack assembly 400, as well. Rack assembly 400 is easily disassembled from cart 1 upon reaching a chosen destination, and the components are conveniently transported within cart 1's storage backpack, such as carry bag 120 shown in FIG. 1.

[0279] Also illustrated in FIG. 26 are stabilizing assemblies 450 and 460. Assembly 450 makes use of post 420, which is friction-fit into an inverted rail clamp 410. Assembly 460 comprises an inverted tubular sleeve 462, optionally permanently welded to the handle assembly crosspiece. Sleeve 462 accepts kickstand post 424 in a similar fashion to rail clamp 410. These assemblies 450 460 serve to brace the cart 1 when it is parked.

[0280] Moreover, kickstand post 424 may be used with any embodiment having a handle, such as handle 80 of FIGS. 12 and 17-19, or handle 81 of FIGS. 32 and 33.

[0281] Turning to FIG. 27, which is highlighted in FIG. 26, an exploded perspective close-up detail view of rail clamp 410 is presented. Clamping block 411 is provided with a bore 412 to receive post 424, an attachment face 413 including a semi bore 414, and notch 415, and threaded bore 416. Plate 417 includes semi bore 418, through hole 419, and protruding rib 420.

[0282] As shown in FIG. 28, when threaded knob 422 is inserted into hole 419 of plate 417 and tightened into threaded bore 416 of block 411, clamping is achieved against frame member 60. Rib 420 is secured within notch 415 by a camming action in the direction of arrow “A”.

[0283]FIG. 29 shows cantilevered hanger clamp 430, poised to slide down upstanding post 424. Hanger clamp 430 is provided with a bore 431, which is notched in a similar manner to clamping receptacles 71 of the handle assembly. The notch separates the body of hanger clamp 430 into two walls. Threaded knob 422 will compress the walls surrounding the notch, thereby tightening bore 431 around post 424. L-shaped region 432 is integrally formed with the body of the hanger clamp, and provides a strong and durable support for transporting hunting or other gear.

[0284]FIG. 30 is a perspective view of an anti-tipping linkage 500, which couples cart 1 to a bicycle. Linkage 500 counteracts cart rollover caused by centrifugal force as the bicycle negotiates turns.

[0285]FIG. 31 illustrates the components of linkage 500. Bicycle seat-stem compression clamp 510 is formed of a body portion 511, and plate 512, fastened by screws 513. Bore 514 is angled so that clamp 510 remains perpendicular when installed on a typical bicycle seat-stem. Clamp 510 is provided with a bore 515 on rear face 516, which accepts a shaft 520. Pin 517 passes through clamp and fixes shaft 520 via a through-bore. Shaft 520 includes through-bore 522 at its distal end. Another through-bore 523 is provided slightly proximal of aperture 522. When shaft 520 is inserted into coil spring 530, hooked leg 531 of the spring will fit into bore 522. A sliding collar 524 will then extend over leg 531 to prevent pull-out, and a pin 526 will be fitted into collar hole 525, and into bore 523 of the shaft 520, thereby securing the collar to the shaft and preventing removal of the coil spring.

[0286] A shaft 540 is provided for the opposite end of coil spring 530. Hooked leg 532 fits into bore 542 of the shaft, and collar 544 slides over and is fixed by pin 546, fitted into collar hole 535 and shaft bore 543.

[0287] Support rails 550 and 551 are fixed to handle clamps 71 of cart 1. The rails are bent into an inverted V configuration, and permanently affixed to block 552. Block 552 is provided with bore 553, into which the free end of shaft 540 is fitted. Pin 555 is inserted into through bore 554 of block 552, and passes through bore 547 of shaft 540, creating the continuous, secure anti-tipping linkage 500 between cart 1 and a bicycle. It is understood that during maneuvers of the bicycle, there will be no problems associated with a typical universal or pivot joint; the coil spring will absorb and disperse any rotational stresses, and will react as a 360° “living hinge”.

[0288]FIGS. 32A-32G, 33 and 33A show an alternate embodiment 600 of the portable cart using four wheels 30 in an overlapped configuration. A hard molded cover 601 is illustrated although any cover or no cover can be used as well. Cover 601 covers bin 602 with lower overlapping edge cap 601 a fitting over peripheral shoulder 602 a of bin 602. Bin 602 also has longitudinally extending concave channels 603, which rest upon rails 604 of cart 600 of FIG. 32. Downward pressure of the weight of bin 602 and its contents helps stabilize bin 602 upon rails 604, which may be optionally covered with rubber or other resilient linearly extending cushions.

[0289] Although FIG. 32 illustrates portable cart 600 with covered bin 602, portable cart 600 can be used with other embodiments, such as, for example, boat cushions 13 shown in FIG. 4, framed rail stretchers 100 as in FIG. 12, the game cart of FIG. 17, the cargo cart of FIG. 18, the conventional rescue carriers of FIGS. 23 and 24 or the gear rack of FIG. 26, among others.

[0290]FIG. 32H shows an exploded inverted view of an alternate embodiment for a ruggedized handle assembly, including handle 630 and handle shaft 626 with spring pin 628 lined up to enter the end of stanchion truss weldment 620. Stanchion truss weldment 620 has two downward extending struts 632, which accommodate axles 624 therethrough, which axles 624, in-turn, attach to wheels 622. Central bushing receptacle 634 accepts the end of handle shaft 626. Receptacle 634 also has a lower pushpin aperture and a pair of opposite holes for a through pin to hold handle shaft in place. FIG. 32H also shows kickstand 640 stowable within handle shaft 626.

[0291]FIG. 32I shows a close-up inverted view of receptacle 634, showing handle shaft 626 located within truss weldment 620, and held in place by spring pin 628 of handle shaft 626 and/or through pin 629.

[0292]FIG. 32J shows a four wheel cargo hauling cart with kickstand 640 attached to kickstand attachment bracket 638, which is part of handle 630. Also shown are stacked cargo bin shell containers 634 held securely by straps 636.

[0293] In the sequence of FIGS. 32K, 32M, and 32N, straps 636 have been detached from bin shell containers 634, and the sequence of removal of top bin 634 is shown ending with a vertically oriented bin drawer cabinet 635 with a cover panel 639 removed, thereby exposing slidably openable drawers 642 on its front surface. FIG. 32N shows drawers 642 behind drawer retaining panel 639 in a cutaway view.

[0294] Lower bin 634 optionally contains related medical supplies for a field hospital, such as power packs, oxygen tanks, and other necessary medical supplies.

[0295]FIG. 32O is an optional hitch assembly 644, which replaces the handle assembly. Hitch legs 646 are received into handle 630.

[0296] Spring pins 651 also participate in this coupling. Connector 646, with hitch tongue 652, form a structure engagable with receiver clevis 653 attached to all terrain vehicle 656. FIG. 32P shows hitch 644 being used to pull cart 632 by all-terrain vehicle 656.

[0297]FIG. 33 shows a perspective view of the frame of cart 600. Long axle 606 attaches front wheels 30 while short axle 605 attaches rear wheels 30 through respective vertical support pairs 20. The use of four wheels doubles the carrying capacity of the cart of this invention while the overlapped positioning of the wheels maintains a short wheelbase for compactness and for maneuverability such as turning with fixed axles and the ability to easily climb ledges. For durability, the rails 604 may be a double pair of parallel rails.

[0298] Double axled cart 600 has increased maneuverability, since user pushing upon an optional handle 81 enables user to lift the farther away, distal pair of wheels 30 off the ground, and the user pulling upward of handle 81 raises the nearer proximal wheels 30 off the ground.

[0299]FIGS. 34 through 39 are concerned with an alternate embodiment of the horizontal load support member 10. The alternate embodiment 610 has an integral T-slot channel 611 in its top surface to facilitate easy installation and removal of a variety of attachments, such as cushions 615 shown in FIG. 35-36, clamps 620, 630, 640, shown in FIGS. 37-39, or platform 1450 shown in FIG. 57. Load member 610 can be conveniently extruded of aluminum or magnesium; it can be used either with the two-wheel cart 1 or the four-wheeled embodiment 600.

[0300]FIG. 35 shows a resilient cushion 615 installed in the T-slot 611 of support member 610. This cushion 615 can be extruded of a variety of rubber or thermoplastic elastomers and serves the same purpose as cushion member 13 described above. A perspective view of FIG. 36 shows cushions 615 installed on a four-wheel cart 600.

[0301] As described above, clamp assembly 200 is used to convert portable cart 1 to a disabled person-bearing transportable carrier cart. Three separate alternate embodiments of clamp assembly 200 are presented; all are compatible with the use of horizontal support member 610.

[0302]FIG. 37 shows a one-piece clamp 620 with full width top section 622 and short end pieces 621, which mate with, and slip into the T-slot 611 of horizontal support member 610.

[0303]FIG. 38 shows clamp 630 with a full width bottom member 631 which mates with and slides into T-slot 611 of horizontal support 610.

[0304]FIG. 39 shows another alternate embodiment consisting of two short identical clamp members 640, which are inserted into the T-slots 611 of member 610 at the two extreme ends.

[0305] In all cases, the short clamping sections can be sized to offer spring-like gripping action on the tubular members, or fasteners, such as thumbscrews or ball plungers (not shown) can be used for retention.

[0306]FIGS. 40-50 show alternate embodiments for converting a conventional hand carried, railed medical rescue stretcher to a lightweight wheeled version.

[0307] For example, FIGS. 40-42 show shortened horizontal support members 710 with tightening members 711. Rails 713 are held either by clamps, such as shown in FIGS. 37-39, or alternatively through apertures in horizontal support members 710, as shown in FIG. 14. Horizontal support members 710 are demountably attached to vertical struts 720 having extending therethrough transverse axles 732 supporting wheels 730. Optional pivotable kickstand 740 is attached to rails 713 by clamp 800.

[0308] As also shown in FIGS. 47-50, clamp 800 includes two jaws 801, 802 having aperture recess 803 for insertion of rails 713 therethrough. Clamp 800 is closed and tightened by fastener 804 operated by rotatable knob 805. Internal spring pins 806, as shown in FIG. 47, cooperate with fastener 804 and knob 805 to tighten clamp 800 about rail 713. Internal grooves 807, 808 accommodate kickstand 740 in the respective positions of support and rest, as shown in FIG. 40 and FIG. 42 respectively.

[0309]FIG. 43 shows an alternate embodiment for a military or emergency rescue carrier cart 900 with a profile set low to the ground, including shortened horizontal members 910 with tightening fasteners 911. Rails 913 are also held by clamps as in FIGS. 37-39, or alternately through apertures in horizontal support members 910, as in FIG. 14. Horizontal support members 910 are demountably attached to shortened vertical struts 920 to keep stretcher rails 913 close to the ground. Optional bent handle 945 is connected by clamps 800 disclosed in FIGS. 47-50, as discussed above.

[0310]FIGS. 45-46 show how the stretcher version shown in FIGS. 40-42 can be converted to a stationary medical gurney 1000. Rails 1013 are supported by horizontal support members 1010, which hare demountably attached to vertical struts 1020, having axles 1032 supporting wheels 1030. To stabilize gurney 1000, horizontally extending tie rods 1036, 1037 are joined by threaded clamp 1038 or other fastening means.

[0311] The major structural components of an alternate embodiment low profile rescue carrier are shown in FIG. 43A. Latch clamps 1800 of stretcher bearing tube assemblies 950 support stretcher 1730 and also engage handles 630 at each end. Handles 630 may be rotated into an upward locking position or downward. Tube assemblies 950 include lateral spring pins 962 and upper spring pins 963 for proper placement of wheel assemblies comprising struts 920 having rail bearing clamps 910 operable by latch handles 911.

[0312]FIG. 43B shows an exploded view of handles 630 engagable with stretcher bearing tube assemblies 950 of FIG. 43A. Handles 630 are attached to short handle shafts 956 with spring pins 958 (as in detail callout FIG. 43C) within. Similarly, a coupling section detailed in FIG. 43C has spring pins 958 installed as shown. Spring pins 958 include bent leaf spring section 960 which tail end impinges on the inside of tube 956 or tube 952 while the other end is attached to spring pin button 962 which protrudes through a hole in the side of tube 956 or 952. Buttons 962 couple with a tube mid sections 954 via holes near the ends of these tubes. Buttons 963 function as wheel set locators and fit into wheel set clamps for proper fixturing, as shown in FIG. 43A.

[0313] The low profile rescue carrier is also shown in the side elevational view of FIG. 43D, which illustrates the feature of the handles 630 rotated to the downward position and functioning as kickstands.

[0314] As shown in FIG. 43E, the low profile rescue carrier is easily converted into a low profile transport rotating handles 630 from the kickstand support position to an upright handle position which is easily grasped by medical personnel. Short handle shafts 956 are shown in the optionally extended position in FIG. 43E, to allow for clearance between the medic and the stretcher. The medic may drag the stretcher 1730 upon stretcher bearing assembly 950 as shown, or alternatively, push or pull the stretcher or other carrier bearing assembly 950 forward by reversing his orientation.

[0315]FIGS. 51-53 show a further embodiment for portable cart 1101 which folds down to a disassembled storage position as in FIG. 51 and which unfolds to an assembled position of use as in FIG. 52. Cart 1101 includes a pair of horizontal load support members 1110 laid parallel to each other, which rotate axially to move perpendicularly extending vertical struts 1120 outward from a position within a storage bag 1101 a, where vertical struts 1120 face each other's distal ends, to a position of use 90 degrees perpendicular to the storage position, where vertical struts 1120 extend in the same plane but outward from horizontal load support members 1110.

[0316] In this embodiment shown in FIGS. 51-53, the resilient rails 1178 are engaged to horizontal supports 1110 such that when in a position of storage the rails 1178 are biased to return to their normal position of use, when released from the storage position, thus causing vertical struts 1120 attached to horizontal supports 1110 to pivot upward and bow, thus increasing the strength of the cart.

[0317] The same is true with other embodiments of the present invention. For example, placing a boat 2 upon cart 1 causes horizontal support members 10 and wheel axles 31 to bow, giving it the strength of an uncollapsible Roman arch. The same is true with respect to stretcher or cargo hauling embodiments shown in FIGS. 12, 17-19, 40-45 and 58-66, for example, wherein putting weight makes the carrier portion taut and bows the frame members into a position of strength. Also the multiple floating overlapping rails as in FIG. 14, for example, bow the rails and strengthen the cart with a load supported thereon.

[0318] Moreover, vertical struts 1120 can be further strengthened in place to horizontal supports 1110 by connecting braces, such as V-shaped braces 1121.

[0319] Wheels 1130 are held by axle 1131, which in a storage position is placed within the storage bag 1101 a. To lengthen cart 1101, rails 1178 move away from each other within holes 1112 within horizontal supports 1110, and are stopped from further movement by spring stop buttons 1171.
